PC won't see my glyph drive after I have installed Mac Drive 8

Control Panel, Computer Management, Disk Management. Check that your Glyph is present. If it is present, does it have a drive letter assigned? If not Right Click and Assign Drive Letter.

If drive not present you should check power and data connections.

If the hard drive was formatted on a PC computer in NTFS file format then the MAC will not recognise this hard drive.
If you want to transfer data between the PC and MAC then you need to format the hard drive with a PC in FAT32 file format. The MAC can read and write to a FAT32 formatted hard drive

Your answer should be in there somewhere as it covers most of the issues with portable hard drives

can you let me whether it shows in bios

Ok mac and oc have two different file systems There fat32 and i forget the refernce for mac they do not see each other But you can ge6t a driver and format the system so it will work to your benefites for get a software drive converter

Did you format the Glyph tabletop harddrive? If you didn't format it, it won't work.

Your Operating System is not stated, so let me give you an example using Windows XP. (Home or Pro doesn't matter)

Power cord plugged into the Glyph harddrive, and plugged into a surge protector, 6-pin Firewire cable, or 9-pin Firewire cable from Glyph to computer plugged in, Glyph power turned on, computer on, Windows loaded,

1.Left-click on Start, then Right-click on My Computer. Left-click on Manage, in the small fly-out menu.

2.In the Computer Management window, under Storage, click on Disk Management. The Write Signature wizard will pop up.

3.Use the wizard to write a signature to the new drive. The drive must be named. Name it what you want. (Drive 2; My Drive; Storage 2: Your name;
whatever you wish)
This drive must be named, or Windows won't be able to find it.

4.Now I suggest just making one partition, and it will be the Primary partition. Do this by selecting the Maximum Size. (Partitioning: Think of your harddrive as a large room. A Partition is a wall, dividing the room into two rooms. This time you won't be dividing the room. You will use the whole room. 250 GigaBytes of it) Choose -> NTFS.
Follow the instructions, let it format the harddrive.

You should be good to go now.

I have added this link, to a PDF file download of the

I had not created even a primary partition for my Glyph drive which I needed to do. So I created a new partition and seleected the maximum size for it which was all 500GB of the drive, since I dont want any real divisions of the drive; then I selected quick format. This is actually on the Glyphtech.com questions on how to format the drive, it will telll you about this step of creating a primary partition (or even more partitions if you want them).

you could try a program like disk warrior or disk rescue, or you could try giving Glyph a call, they have pretty good warranty coverage.

If the drive is connected via firewire, power the drive. If the drive powers and you can place your hand on it and feel it "spinning", and still it does not mount. Try a different FW cable. If still no mounting action, place your ear on the drive to hear any grinding or clicking. If the drive sounds to be operating normal, open disk utility.. Hard drive/Applications/Utilities/Disk Utility The drive should appear in the left pane under your computers hard drive. You should see the button to MOUNT it on the top right. Hope this works
